Do you believe in ghosts/spirits? If so, why?

Question by : Do you believe in ghosts/spirits? If so, why?
This is just out of curiostiy. :p Don't just put "yes" or "no," leave reasons why. By spirits, I mean any kind of spirit: angel, demon, "elementals," doppelgangers, poltergeists...anything that can classify as a "spirit," save the "human spirit."

As for myself, I don't personally believe in spirits or ghosts, but I'm not going to rule out their existence necessarily. I just don't really believe in them, but if there was concrete evidence, I might be more willing to believe in their existence.
